chris444123 Posted July 10, 2015 Share Posted July 10, 2015 I own a pair of RC-7 centre speakers, now I want to use the drivers and horn to build normal floorstanders. I've checked the specs and I'm confused, the horns where used in some models and also the subs where used in some models, but never combined in one floorstander. Does anybody have an idea how to get this fixed, what kind of housing and what kind of crossovers should I use? Quote Link to comment Share on other sites More sharing options...
wvu80 Posted July 10, 2015 Share Posted July 10, 2015 (edited) Hi Chris, welcome. I'm not sure what you mean by "build normal floorstanders." Are you thinking tall skinny enclosures that have the two woofers on the bottom and the horn on the top? Those RC-7's are outstanding speakers and the D'Appoloto MTM design is very highly respected and can give you a very good sound. I would use them vertically and put them on stands if you wanted to get that horn to ear level. One of the problems you may run into if you take those RC-7's apart is that the woofers each have separate crossover points. If you change the enclosure you are going to be changing the original design parameters, and I really don't know how that will sound. Here is a top-of-the-line crossover for an RF-7. I don't know if it would work properly for the RC-7 components, but if it would, this XO would be outstanding. https://community.klipsch.com/index.php?/topic/157816-rf-7-point-to-point-soldered-crossovers-with-audiocap-ppt-thetas/ Edited July 10, 2015 by wvu80 1 Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted July 10, 2015 Share Posted July 10, 2015 It sounds like he's trying to build RF-5's. 1 Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted July 10, 2015 Share Posted July 10, 2015 The enclosures you have are optimized for that driver combination. The best, easiest and cheapest thing for you to do is get a pair of speaker stands that will put the tweeter at ear level when you turn the RC-7 on end and listen to them that way. 1 Quote Link to comment Share on other sites More sharing options...
chris444123 Posted July 14, 2015 Author Share Posted July 14, 2015 Thanks for the tips. I already put them on speaker stands, however, and indeed I would like to build them like the RF-5, the speakers miss some high and mid. I tried several things, and no matter how I trie, the low is not extremely low, the mid sounds weaker and the high also sounds less strong. i know they are centres and for that purpose they are really good. Bright voices, good positioned. So yes indeed I'm looking for a new crossover module and cabinet layout. Quote Link to comment Share on other sites More sharing options...
wvu80 Posted July 14, 2015 Share Posted July 14, 2015 Do you run a subwoofer? That would certainly boost the lowest frequencies the RC-7's don't cover, and it will help reinforce the bass sound the RC-7's do have. The way you describe the C-7's (which I have never heard) it sounds like they simply do not have the sonic characteristics you are looking for. If that is the case, taking them apart and re-using the same drivers in a different enclosure is not likely to improve anything, and in fact I think it is more likely you will be spending a lot of time and money to make them sound worse. Any resale value for them at that point would be very little compared to stock. I would suggest you sell the C-7's and simply buy some other speakers that are more to your musical tastes. 1 Quote Link to comment Share on other sites More sharing options...
chris444123 Posted July 14, 2015 Author Share Posted July 14, 2015 (edited) They sound good, don't get me mistaken. An option I have is to buy a pair of RF-83's, I'm gonna listen to them tomorrow. The characteristics I'm looking for is a well balanced overall, eg if you listen to an orchestra you should hear all instruments in there full spectrum, the highs from the violins to the lows of the hobo or contra bass. == edit, Yes I run two subs for the support two RW-8's, much lower volume than the RC-7's. The reason why I choose the Klipsch is the right in your face live experience they have. Edited July 14, 2015 by chris444123 Quote Link to comment Share on other sites More sharing options...
Ceptorman Posted July 14, 2015 Share Posted July 14, 2015 I have a feeling you will like the RF83s. Quote Link to comment Share on other sites More sharing options...
chris444123 Posted July 22, 2015 Author Share Posted July 22, 2015 I bought the RF-63's. Still getting used to the sound. Think I have some issue's with my receiver, they dont blow as they should. Receiver: Marantz SR4400 Any suggestions for a replacement receiver? Budget € 500,= I was thinking of: ONKYO TX-NR636 Quote Link to comment Share on other sites More sharing options...
MORE KLIPSCH PLEASE Posted July 22, 2015 Share Posted July 22, 2015 (edited) I'm with wvu80 on this.... Did you sell RC-7's ?? MKP :-) Edited July 22, 2015 by MORE KLIPSCH PLEASE Quote Link to comment Share on other sites More sharing options...
chris444123 Posted July 22, 2015 Author Share Posted July 22, 2015 No I still have the RC-7's, and also the subs, they are for sale, but unlikely to ship them to the US, I'm from Europe. Quote Link to comment Share on other sites More sharing options...
longdrive03 Posted July 22, 2015 Share Posted July 22, 2015 I know the cows just left the barn but thought I would address the question posed. You could take the RC7 components and place them in a larger box and get lower bass response (probably without changing the crossover but Dean and others can chime in). I built a larger CC for a guy using the RC7 components and the bottom end was stronger. Specs on the K1083 woofers ar 43 hz fs, .36 qt, 35 lit vas. They are 8 ohm (6.3ohm revc). Once you have the T/S specs you can use various programs to run cabinet size and port dimensions if you want to go that route. Dean G can probably help with a mod on the tweeter end if you contact him. Good luck Quote Link to comment Share on other sites More sharing options...
chris444123 Posted July 23, 2015 Author Share Posted July 23, 2015 I have the 63 knows as mentioned. What will happen to the sound if i fill the 3 holes in the back and drill new ones in the front of the speaker? Will i **** them up? I have them situated 2 mtrs or 7 feet from a wall.

The History Kid Posted July 23, 2015 Share Posted July 23, 2015 Just to add my two cents, do not forget they are center channel speakers, speakers designed for voice. Your lows are not going to be hard hitting and in your face with a speaker such as a center - no matter how you cut it. That's why many run 3 of the same speaker across the front, so not only is the sound seamless across the front stage, but you also have more depth to the center. I would echo what others are saying and just sell the 7's. Quote Link to comment Share on other sites More sharing options...
chris444123 Posted July 23, 2015 Author Share Posted July 23, 2015 I was not talking about drilling holes in the centres. I sold one, the other one i will keep, for movies etc Quote Link to comment Share on other sites More sharing options...

Why would you want to do that? You have prime space estate to use the rear-firing ports. Front firing speakers I find...are...bleh. Quote Link to comment Share on other sites More sharing options...
